Imprinting Quantum Fluctuations on Hydrodynamic Initial Conditions

We have developed an algorithm to imprint quantum fluctuations onto the initial transverse energy density profile according to a given two-point covariance function. Using as an example MC-KLN initial conditions with added fluctuations satisfying the covariance function derived in [1], we find that effects from sub-nucleonic gluon field fluctuations on the eccentricity harmonics epsilon(n) vary strongly with the gluonic correlation length controlled by the saturation momentum Q(s). Varying Q(s) over the range probed in Au+Au collisions at RHIC, we find gluon fluctuation induced enhancements of the eccentricity coefficients ranging from 10 to 20% in central collisions.
